x-intercept is (18,0)
y-intercept is (0, 9)
See below

Explanation:

Plug in 0 for y to find the x-intercept:

x=18

Plug in 0 for x to find the y-intercept:

2y=18

Solve for y:

y=9

So we have the two points, (18,0) and (0,9). So we can just connect the dots:

graph{x+2y=18 [-16.73, 23.82, -6.9, 13.38]}
